The main problem in the conventional total mixed ration (TMR) is the higher moisture content. The high moisture content of TMR will encourage the mould and yeast at the pellet. It is also can lead to feeding waste because many nutrients are broken down into undesirable materials during the overheating phase. Furthermore, the wet substance can overheat at average temperature and spoil instantly when exposed to higher ambient temperature. To overcome these problems, proximate analysis and shelf life of TMR were discussed in this study. The chemical composition of the pellet in different timeline, day 0, 15, 30, 45 and 60 were determined using proximate analysis. For statistical analysis, the data was analysed using one-way analysis of variance (ANOVA). The result of crude fibre content in day 60, 45, 30, 15 and 0 was 2.964, 3.023, 5.129, 12.451 and 27.256 respectively. Next, the value of crude protein in day 0, 15, 30, 45 and 60 were 10.283, 9.889, 8.492, 13.195 and 1.136 respectively. Then, the result of fat content that started with 5.446 in day 0, 4.173, 3.427, 2.157 and 1.499 in day 15, 30, 45 and 60 respectively. Furthermore, dry matter result start with 93.727 in day 0 and continued with 93.473, 93.34, 92.791 and 91.142 in days 15, 30, 45 and 60 respectively. Next, in day 0 and 15, the moisture content was 6.527 and 6.273 respectively. However, in days 30, 45 and 60, the value of moisture content pellet was 6.527, 7.67 and 8.037 respectively. Lastly, result of ash analysis in day 15 is 7.738 and in day 30, 45 and 60 which were 6.487, 3.906 and 3.563 respectively.
